In May of 2004, the Civilian Space Exploration Team (CSXT) launched a 21-foot long rocket to an altitude of 72 miles. The “Go Fast” rocket became the “first American civilian sounding rocket to reach outer space” and the first verified launch into space by an amateur group.

To celebrate the tenth anniversary of the achievement, the CSXT did it again.

The rocket carried a military grade Inertial Measurement Unit (IMU) which had previously flown on four commercial space missions launched from the White Sands Missile Range (WSMR). Analysis of the data from the recovered IMU shows that the GoFast rocket reached 385,800 feet (73.1 miles) with a top speed of 3,580 miles per hour.
